Learner Data from a Study on Latin Language Learning

The dataset contains test results from a digital intervention study of the CALLIDUS Project in a high school in Berlin. 13 Students were randomly sampled in two groups and completed various linguistic tasks. The focus of the study was to find out whether learning Latin vocabulary in authentic contexts leads to higher lexical competence, compared to memorizing traditional vocabulary lists. The data is available in JSON format as provided by the H5P implementation of XAPI. File names indicate the time of test completion, in the concatenated form of "year-month-day-hour-minute-second-millisecond". This allows us to trace the development of single learners who were fast enough to perform the test twice in a row. Changelog: Version 2.0: Each exercise now has a unique ID that is consistent in the whole dataset, so evaluation/visualization can refer to specific exercises more easily.本数据集收录了柏林某高中开展的CALLIDUS项目数字化干预研究的测试结果。研究招募13名学生并将其随机分为两组，所有学生均完成了多项语言任务。本研究的核心目标为探究：相较于背诵传统词汇表，在真实语境中学习拉丁语词汇是否能够提升学习者的词汇能力。 本数据集以JSON格式提供，由XAPI的H5P实现生成。文件名采用"年-月-日-时-分-秒-毫秒"的拼接形式标注测试完成时间，借此可追踪那些能够连续完成两次测试的单个学习者的能力发展轨迹。 更新日志：版本2.0：所有练习均新增全局唯一ID，且在全数据集内保持一致，便于评估与可视化环节更便捷地指向特定练习。
